API
* The method signature of get, getByKey, getMulti, and getMultiByKey changed.
* get* and getMulti* commands no longer take cas or user flags parameters.
* get* and getMulti* commands now take the Memcached::GET_EXTENDED flag to retrieve user flags and cas tokens.
* Fixes getStats command to return all stats from all servers
* Fixes allKeys command behaviour
* Fixes error where cache callback for get command was not setting expiration time properly
* Added server type to server list
* Remove use_sasl ini-variable and initialise sasl as needed
* CAS tokens are returned as integers and they overflow to strings as needed

Session handler
* The session memcached protocol config name was changed, and the default protocol was changed from text to binary protocol. If your memcached setup does not support the binary protocol(e.g. if using twemproxy), then set memcached.sess_binary_protocol = Off. (Previously called memcached.sess_binary)
* Session lock algorithm updated (new ini-values memcached.sess_lock_wait_min, memcached.sess_lock_wait_max and memcached.sess_lock_retries)
* Session extension uses PHP allocators (still some work to do on the rest of the extension)
* Ini-values take effect during session_start or session_regenerate_id
* Fixes crash with session_regenerate_id (work-around for PHP bug)

- Add OPT_REMOVE_FAILED_SERVERS option.
- Make it work with libmemcached up to 0.49.
- Fix a case where invalid session ID could lock the script.
- Improve session support:
* Add support for libmemcached config string
* Add persistence support via PERSISTENT=persistent_id prefix
of the save_path
- Add 3rd parameter to the __construct() that allows specification
of libmemcached configuration string
- Fix a possible crash in __construct() when using persistent
connections
- Add work-around a bug in libmemcached < 0.50 that causes truncation
of last character of server key prefix
- When using multiple servers implement transparent fail-over
- Fix php_memc_cas_impl() implementation when server_key is not being used
- Add support for incrementByKey() and decrementByKey()
- Make increment/decrement initialize value when it is not available (when
using binary protocol)

- Refactor the way payload types are stored in memcached flags to optimize the structure
and allow for future expansion. WARNING! You have to flush the cache when upgrading from
an older version.
- Add JSON serializer support, requires PHP 5.2.10+.
- Add HAVE_JSON and HAVE_IGBINARY class constants that indicate whether the respective
serializers are available.
- Add 'flags' parameter to getMulti() and getMultiByKey().
- Add GET_PRESERVE_ORDER class constant that can be used with abovementioned flags
parameter to make the order of the keys in the response match the request.
- Fix an issue with retrieving 0-length payloads (FALSE boolean value).
- Add several tests.
